Frequency Bands

Larsen amateur antennas are available in the following bands:

10m 28 - 30 MHz 6m 50 - 54 MHz 2m 144 - 148 MHz 1.25m 220 - 225 MHz 70cm 440 - 450 MHz 35cm 902 - 928 MHz

Not all antennas are available in all bands. Consult the product listings for specifications.

Electrical Types

Choosing the proper antenna for any application requires carefully weighing these criteria: • Gain • Physical Size • Cost • Appearance

The gain required depends on system margins and how far the system must operate. Generally, the more gain, the more cost and the longer the antenna. Systems where the antenna can be a low performance type will have less cost and less noticeable antennas at any particular frequency. Installations with a suitable ground plane will have the same performance at less cost than those without adequate ground plane.

To determine the best mobile antenna types to use in a particular installation, you should first be acquainted with all the electrical types available. Keep in mind not all types are available in all mechanical configurations and frequencies.

Loaded 1/4 Wave The loaded 1/4 wave antenna is electrically a 1/4 wave but is shorter than a full size 1/4 wave antenna. This is accomplished with a loading coil which places a portion of the electrical length of the antenna in a coil located at the base of the radiating element. The efficiency of the antenna depends on how much of the electrical length is inside the coil (and there- fore not radiating). Typical gain is comparable to a full 1/4 wave where the full 1/4 wave is mounted on the fender and the loaded 1/4 wave is mounted on the roof. Typical length at the lowest recommended frequency is 49”.

1/4 Wave A single radiating element 1/4 wavelength long. It is the simplest and least expensive type of antenna. Length varies from 20” at 144 MHz to 3” at 900 MHz. A loading or matching coil is not required. Typical gain is unity when mounted on a suitable ground plane.

4 www.pulseelectronics.com/products/antennas Technical Guide

1/2 Wave The 1/2 wave antenna is a single radiating ele- ment 1/2 wavelength long. Because the end fed impedance of the antenna is not suitable for matching the radio, an impedance match- ing transformer is used at the base of the radiating element. Length varies from 49” at 120 MHz to 13” at 440 MHz. The 1/2 wave antenna is suitable for use where no ground plane exists. The gain with no ground plane is unity. Gain with a suitable ground plane is 2.4 dBi.

5/8 Wave The 5/8 wave antenna is a single radiating ele- ment 5/8 wavelength long. In single element antennas, the 5/8 wave antenna has the best performance (3 dB) when mounted on a suit- able ground plane. Element length varies from 49” at 144 MHz to 18” at 440 MHz. Since the end fed impedance of a 5/8 wave antenna is not suitable with a radio, an impedance trans- former is used at the base of the rod. Must be mounted on a suitable ground plane.

Collinear Two elements separated by a phasing coil for increased gain. Three styles are common:

5/8 over 1/2 These collinear designs have two elements separated by a phasing coil. 5/8 over 1/4 The top element is 5/8 wave and the bottom element is either a 1/2 wave or a 1/4 wave. Gain is typically 5 dB for a 1/2 wave lower element and 3-4 dB with a 1/4 wave lower element when mounted on a suitable ground plane. Antenna length is 23” to 29” at 440 MHz depending on the lower element. The end feed impedance matches the transmitter’s impedance, so no trans- former is used.

5/8 over 5/8 This collinear design has two elements separated by a phasing coil. Both top and bottom elements are 5/8 wave. Gain is typically 5 dB when mounted on a suitable ground plane. Collinear element length is 33” at 440 MHz. The end fed impedance does not match the transmitter’s impedance, so a trans- former is used

All Larsen antennas operate with a VSWR of 1.5 to 1 or less across the transmit bands.

1 800 ANTENNA (268-3662) 7 Portable Radio Antennas Electrical Styles

To determine the best portable antenna to use in a particular application, you should first be acquainted with all the electrical styles available. Keep in mind not all types are available in all mechanical configurations and frequencies.

Helical This most commonly used style is available in the widest range of frequencies — 136-221 MHz — and is carefully made for top performance. Helical antennas are wound with .050” steel wire and jacketed with copper plating for the best performance. Cover- ings include polyolefin for low dielectric loss and an outer wrap of PVC for good looks and rugged wear.

HQ Helical 1/4 Wave For VHF applications requiring peak performance in the 144-148 MHz range while toler- ating a length slightly longer than helical types. This unit provides an excellent compro- mise for many applications. It has a lower helical section with the upper element made from brass wound cable with a flexible shaft core to prevent breakage or brittleness. The HQ operates as a loaded 1/4 wave antenna.

8 www.pulseelectronics.com/products/antennas Portable Radio Antennas 2/70 Dual Band The 2/70 series Kūlduckie® portable antenna offers superb performance for dual band (2 meter / 70 centimeter) handheld radios. The antenna operates as a full 1/4 wave at 440-450 MHz and a loaded 1/4 wave at 144-148 MHz. Construction elements include a brass wound steel flexible core radiating element. The loading coil is housed in sturdy polycarbonate plastic for long life.

HW UHF 1/2 Wave For UHF applications requiring maximum performance, the HW series is unmatched. It employs a resonant 1/2 wave design which allows it to operate independently of radio ground plane, and generates performance equal to a full 1/4 wave on a perfect ground plane. The rigid impedance transformer at the base contributes to optimum perfor- mance and adds extra strength. The HW-UHF model features a 1/2 wave whip with construction similar to the 1/4 wave model. The HW-UHF mounts with a BNC Male con- nector for easy on and off.

1/4 Wave The full 1/4 wave style is a high performance antenna for UHF ranges of 440-450 MHz. It is constructed with a flexible steel core and electrically efficient brass wound cable. This special, flexible cable design assures excellence and durability under the most de- manding conditions.

1 800 ANTENNA (268-3662) 15 Mobile Antenna Placement

t Larsen we want our customers to be confident they can find the right antenna for the right application. AFor this reason, we have provided some guidelines for mobile antenna selection.

When selecting a mobile antenna, there are a number of factors which significantly affect the ultimate performance of the antenna. Gain requirements, electrical type, ground plane availability, mounting style and placement, coaxial type and loss ratings, physical size, appearance and surrounding environment are issues to be addressed to ensure the maximum performance from a mobile antenna installation.

For over 40 years, Larsen engineers have been designing high-performance mobile antennas in a variety of electrical types and configurations to meet the most demanding performance criteria and operating conditions. The electrical type or design of the mobile antenna is commonly referred to in terms of its wavelength: 1/4 wave, 1/2 wave, 5/8 wave, etc. Each electrical type has a specific radiating pattern to be considered when selecting a mobile antenna. For example, the signal radiating from a 1/4 wave antenna is directed more vertically, thus mak- ing it ideal in urban environments where buildings might obstruct the signal. A 5 dB collinear mobile antenna is designed to direct the signal more towards the horizon. This type of antenna is ideal for geographically flat regions where signal coverage is sparse.

Ground plane availability is another critical factor in mobile antenna performance which must be considered when determining the location and type of the antenna. Ground plane requirements vary given the type of mobile antenna and the frequency of operation. A typical 5/8 wave antenna at 150 MHz requires a ground plane at least 42” in diameter. At 450 MHz a 15” diameter ground plane is required, At 800 MHz a minimum of 8” is considered sufficient.

In terms of mounting mobile antennas on a vehicle, there are five general locations: roof, front fender, rear fender, trunk and rear window glass (although other glass mount locations may be used). Of these, the center of an automobile roof is considered the best for mobile antenna placement, followed by the center of the trunk lid, the fenders, then on-glass mounting. This ranking is determined by the amount of ground plane provided by the positioning and clearance from obstruction (i.e., the roof line). The center of the roof is considered the ideal mounting location, provided the roof is metal. The diagram below illustrates the effective loss (at 800MHz) due to insufficient symmetrical ground plane.

Larsen provides a complete selection of permanent and temporary mounting alternatives, using only the highest quality materials to ensure superior electrical performance and mechanical durability. They include magnetic mounts (MM, MS), trunk gutter brackets (TMB), mirror mount brackets (MB) and, of course, traditional permanent hole mounts for all antenna series.

A Successful Installation

A successful installation means that all product instructions are read, the right tools are available, and best practices applied. Below are a few tips to ensure your antenna performs as specified.

NMO Mounts: One way of ensuring proper grounding of your antenna system is to clear the paint on the underside of the mounting surface, such as the roof or trunk, with a medium grit sandpaper or other by other means. The NMO mounting hardware is designed to “cut” into the paint, however, paint thickness and total applied mounting torque may make conditions where grounding is insuf- ficient. The VSWR of the mounted antenna is the primary indicator that the ground is poor.

Glass Mounts: Glass mounts have very specific instructions for preparing the glass for an on-glass antenna and should be strictly followed. The most important instructions are to clean the glass avoiding ammonia-based cleaners, glass temperature must be close to room temperature (70 degrees), and after install, the whip should remain off and the mount dry for 24-72 hours. By preparing and installing correctly, you can rest assured knowing that your antenna is not going anywhere.

Tuning: Many users trust that the cutting charts provided with an antenna are absolute. It should be reinforced that cutting charts are guidelines. Ground plane size (a car versus a van), antenna mounting locations (the roof versus the trunk), and even mounting types (permanent roof mount versus magnetic mount versus trunk lip mounts) all have an impact in the tuning of an antenna. Using the cut chart with an economic SWR meter will help ensure the antenna is tuned correctly.

This cable serves well as a high-quality, low-cost coax for most applications below 512 MHz. Typical loss figures (per 100’ of cable) are 6.8 dBd at 150 MHz and 12.9 dBd at 450 MHz. Due to it’s relatively high loss at higher UHF frequencies (18.3 dBd per 100’ at 825 MHz), it is not usually Stranded recommended for use above 512 MHz. The stranded center Polyethylene Braided Center Dielectric PVC Jacket conductor offers very good flexibility and long life under Conductor Conductor most conditions. Jacket material: Black PVC. Insulator material: Solid Polyethylene.

RG-58 A/U Dual Shield, Stranded Larsen Part Number: DSCOAX

RG-58 A/U coax employs two shields consisting of a full 100% aluminum/mylar wrap covered by a braid. This combina- Shield tion of shields, plus low-loss dielectric material and strand- ed center conductor makes an excellent choice for mobile applications. It has the right combination of low-loss (12.6 dBd per 100’ at 825 MHz), excellent flexibility and uses Stranded Polyethylene standard connectors. Jacket material: Black PVC. Insula- Center Braided PVC Jacket Conductor Dielectric Conductor tor material: Foam Polyethylene. Larsen products using this coax are identified by “DS” in the part number.

RG-58/U Dual Shield, Solid Larsen Part Number: UDCOAX

This is Larsen’s premium coax for 800 and 900 MHz applications. The solid center conductor (20 AWG) is 100% easy to use with all connectors. Digital applications in Shield particular benefit from the 100% Duofoil aluminum shield. The shield is not glued to the dielectric making it easier to peel back for connector installation. The braid is 95% coverage. Jacket material: Black PVC. Insulator materi- Solid PVC Jacket al: Polyethylene. This cable is standard for most mount- Polyethylene Braided Center Dielectric ing kits used for 800 MHz and can be special ordered for Conductor Conductor use with other frequencies. Larsen products using this coax are identified by “UD” in the part number.

RG-213, Stranded Larsen Part Number: RG213

This RG-8-size coax uses a stranded center conductor, polyethylene dielectric and non-contaminating black PVC jacket making it ideal for outdoor applications where it will be exposed to ultraviolet light. Loss per 100’ is from 2.7 dBd Stranded at 150 MHz to 8 dBd at 900 MHz. Polyethylene Braided Center Dielectric PVC Jacket Conductor Conductor

hen it comes to installing antennas, installers face new challenges every day. Automobile manufacturers Wcreate sleek new designs with curved surfaces utilizing less and less metal. In addition, people are less willing to drill a hole in expensive new cars. This creates problems when trying to install an antenna to achieve maximum performance.

Larsen, recognizing this issue, has developed a full line of permanent and temporary mounts to solve virtually every installation need. Each Larsen mount is manufactured of the highest quality materials, including premium coax.

Note: Connectors are shipped loose/uninstalled with all mounting kits except MMR magnetic mounts. An FME universal adapter is installed on all kits.
